His Small House Contained A Collection Of Things The Most Various, But Which Were All Calculated To Interest Travellers.

We found works of literature and natural history; notes on meteorology; skins of the jaguar and of large aquatic serpents; live animals, monkeys, armadilloes, and birds.

Our host was principal surgeon to the royal hospital of Porto Cabello, and was celebrated in the country for his skilful treatment of the yellow fever. During a period of seven years he had seen six or eight thousand persons enter the hospitals, attacked by this cruel malady. He had observed the ravages that the epidemic caused in Admiral Ariztizabal's fleet, in 1793. That fleet lost nearly a third of its men; for the sailors were almost all unseasoned Europeans, and held unrestrained intercourse with the shore. M. Juliac had heretofore treated the sick as was commonly practised in Terra Firma, and in the island, by bleeding, aperient medicines, and acid drinks. In this treatment no attempt was made to raise the vital powers by the action of stimulants, so that, in attempting to allay the fever, the languor and debility were augmented. In the hospitals, where the sick were crowded, the mortality was often thirty-three per cent among the white Creoles; and sixty-five in a hundred among the Europeans recently disembarked. Since a stimulant treatment, the use of opium, of benzoin, and of alcoholic draughts, has been substituted for the old debilitating method, the mortality has considerably diminished. It was believed to be reduced to twenty in a hundred among Europeans, and ten among Creoles;* even when black vomiting, and haemorrhage from the nose, ears, and gums, indicated a high degree of exacerbation in the malady. (* I have treated in another work of the proportions of mortality in the yellow fever. (Nouvelle Espagne volume 2 pages 777, 785, and 867.) At Cadiz the average mortality was, in 1800, twenty per cent; at Seville, in 1801, it amounted to sixty per cent. At Vera Cruz the mortality does not exceed twelve or fifteen per cent, when the sick can be properly attended. In the civil hospitals of Paris the number of deaths, one year with another, is from fourteen to eighteen per cent; but it is asserted that a great number of patients enter the hospitals almost dying, or at very advanced time of life.) I relate faithfully what was then given as the general result of observation: but I think, in these numerical comparisons, it must not be forgotten, that, notwithstanding appearances, the epidemics of several successive years do not resemble each other; and that, in order to decide on the use of fortifying or debilitating remedies, (if indeed this difference exist in an absolute sense,) we must distinguish between the various periods of the malady.

The climate of Porto Cabello is less ardent than that of La Guayra. The breeze there is stronger, more frequent, and more regular. The houses do not lean against rocks that absorb the rays of the sun during the day, and emit caloric at night, and the air can circulate more freely between the coast and the mountains of Ilaria. The causes of the insalubrity of the atmosphere must be sought in the shores that extend to the east, as far as the eye can reach, towards the Punta de Tucasos, near the fine port of Chichiribiche. There are situated the salt-works; and there, at the beginning of the rainy season, tertian fevers prevail, and easily degenerate into asthenic fevers. It is affirmed that the mestizoes who are employed in the salt-works are more tawny, and have a yellower skin, when they have suffered several successive years from those fevers, which are called the malady of the coast. The poor fishermen, who dwell on this shore, are of opinion that it is not the inundations of the sea, and the retreat of the salt-water, which render the lands covered with mangroves so unhealthful;* (* In the West India Islands all the dreadful maladies which prevail during the wintry season, have been for a long time attributed to the south winds. These winds convey the emanations of the mouths of the Orinoco and of the small rivers of Terra Firma toward the high latitudes.) they believe that the insalubrity of the air is owing to the fresh water, that is, to the overflowings of the Guayguaza and Estevan, the swell of which is so great and sudden in the months of October and November. The banks of the Rio Estevan have been less insalubrious since little plantations of maize and plantains have been established; and, by raising and hardening the ground, the river has been confined within narrower limits. A plan is formed of giving another issue to the Rio San Estevan, and thus to render the environs of Porto Cabello more wholesome. A canal is to lead the waters toward that part of the coast which is opposite the island of Guayguaza.

The salt-works of Porto Cabello somewhat resemble those of the peninsula of Araya, near Cumana. The earth, however, which they lixivate by collecting the rain-water into small basins, contains less salt. It is questioned here, as at Cumana, whether the ground be impregnated with saline particles because it has been for ages covered at intervals with sea-water evaporated by the heat of the sun, or whether the soil be muriatiferous, as in a mine very poor in native salt. I had not leisure to examine this plain with the same attention as the peninsula of Araya. Besides, does not this problem reduce itself to the simple question, whether the salt be owing to new or very ancient inundations? The labouring at the salt-works of Porto Cabello being extremely unhealthy, the poorest men alone engage in it. They collect the salt in little stores, and afterwards sell it to the shopkeepers in the town.

During our abode at Porto Cabello, the current on the coast, generally directed towards the west,* ran from west to east.
